Turso

Turso brings the simplicity of SQLite to distributed, edge-scale applications. It is built on libSQL, an open-source fork of SQLite that keeps the SQLite file format and query surface while adding the capabilities a hosted, networked database needs: remote access over HTTP, replication, encryption at rest, and vector search. Because access happens over HTTP rather than a persistent connection, it fits serverless and edge runtimes where connection pooling is awkward.

Its defining pattern is embedded replicas. An application can keep a local SQLite copy of the database that syncs with a remote primary, so reads are served from local storage at microsecond latency while writes propagate to the primary. This is a strong fit for local-first apps, multi-tenant SaaS where each customer gets an isolated database, and mobile or edge workloads that need offline-capable reads.

Turso pairs well with TypeScript ORMs such as Drizzle and Prisma, which both ship libSQL drivers. The company is also building Turso Database, a from-scratch Rust rewrite of SQLite (formerly Project Limbo, MIT-licensed and in beta) that adds concurrent writes through MVCC, async I/O, and native vector search. Turso Cloud is billed on active usage rather than database count: a free tier covers several gigabytes of storage and hundreds of millions of row reads a month, and paid plans raise storage, row limits, and support, with point-in-time restore and branching on every plan.
